Hi folks,
As always, the games’ “forever homes” are all set up at the IF Archive, with permanent URLs: https://ifarchive.org/indexes/if-archive/games/competition2019/
I encourage authors (and anyone else who feels like practicing some metadata heroics) to link their games’ IFDB entries to the appropriate, game-specific archive URLs. That will do a lot to clear up those lonely There are no known download links for this game messages.
